Abstract

Disclosed herein are techniques for generating and signing line-of-code behavior and relation models. Techniques include identifying executable code for a controller; performing a functional analysis of the executable code to determine a plurality of functions associated with the executable code and a plurality of relationships between the plurality of functions; generating, based on the determined plurality of functions and plurality of relationships, a line-of-code behavior and relation model for the executable code; performing a signature operation on the generated line-of-code behavior and relation model to produce a unique signature value associated with at least one of: the line-of-code behavior and relation model or a functional block of the line-of-code behavior and relation model; and linking the unique signature value to the line-of-code behavior and relation model.
